PANIC BUTTON

Press the PANIC button to reset the USB connection to the computer. This is useful if the BMπHP becomes unresponsive to its software plugin either by not processing audio or no longer responding to control movement or automation.

USB 2.0 TYPE B PORT

Standard USB port located on the rear panel. Connect the supplied USB cable, or any other standard USB cable, to this port to provide both power and a data connection the BMπHP. You must connect the USB cable to the BMπHP to use it as a Hardware Plugin. Power for the BMπHP may be obtained from the USB cable or from the supplied AC Adapter.

9V POWER JACK

Plug the output of the factory-supplied EHX9.6DC 200mA AC adapter into the 9V power jack. The BMπHP draws 120mA at 9VDC with a center negative plug. The BMπHP accepts Boss® and Ibanez® style AC Adaptors capable of delivering at least 150mA.

STEREO HEADPHONE OUTPUT JACK

1/4” stereo output jack located on the rear panel. Both the Left and Right Output jack signals are also routed to the Headphone output jack. Use the Headphone LVL knob to adjust the volume at the Headphone jack.

DIRECT MONITOR ILLUMINATED BUTTON

When enabled, DIRECT MONITOR sends the signal headed to the ADC to the stereo output jacks and to the Headphone output located on the rear panel. This is particularly useful when using the BMπHP as a USB audio interface for recording new audio tracks. Note: the DIRECT MONITOR switch is disabled when using the BMπHP as a standalone guitar pedal. In this case, the audio output is always sent to the stereo output jacks and Headphone output.

HEADPHONE LEVEL KNOB

Controls the volume level at the Headphone output jack on the rear panel.

USB STATUS LIGHT

Lights red when the BMπHP is locked onto your computer’s USB. The same LED lights green when a proper audio connection has been made between the software plugin and the Hardware Plugin.

USB GAIN KNOB

Controls the signal level of the audio sent to the computer before it hits BMπHP’s internal A/D converter (ADC). Rotate GAIN clockwise until you see one or both CLIP LEDs light. Then rotate it counter-clockwise a bit so that the CLIP LEDs remain off. This will ensure a large enough analog signal is converted to digital audio without exceeding the digital audio’s total range.

CLIP L & R LEDS

LEDs will light when the audio signal into the ADC is clipping. If the LEDs light up, the audio signal is too loud for the ADC and the digitized audio signal will be distorted on its loudest peaks. Use the GAIN knob to set the right amount of signal into the ADC

VOLUME KNOB

Output volume control for the Big Muff section.

SUSTAIN KNOB

Adjusts the amount of sustain and distortion.

TONE KNOB

Provides a range of sounds from high treble to deep bass. As you turn the TONE knob clockwise, treble increases and bass decreases.

TONE BYPASS ILLUMINATION BUTTON

When enabled, the BYPASS button completely bypasses the Big Muff’s TONE knob and analog EQ, essentially removing the TONE knob from the circuit. When the BYPASS button is disabled, the TONE knob is active and will allow users to sculpt their Big Muff sound. Press the BYPASS button to enable or disable Tone Bypass. If the button is lit, the TONE knob and its circuitry is bypassed.

TONE WICKER ILLUMINATION BUTTON

The Wicker effect opens up the Big Muff’s bandwidth allowing more high frequency signal to pass through for a bright and clear top end. Disable Wicker to obtain the classic Big Muff π sound. Press the WICKER button to enable or disable the Wicker effect. If the button is lit, the Wicker effect is enabled.

PRESET KNOB & DISPLAY

The single digit LED display indicates the current preset number selected using the preset knob. The PRESET is active if the LED above the PRESET footswitch is lit. If this LED is not lit then you are in LIVE mode, where the current knob positions indicate the actual Big Muff setting.

R INPUT

Instrument/Line level, 1/4” unbalanced input jack. Plug your instrument or output from another effects pedal into this jack. Use this jack with the MONO/L INPUT jack for stereo use. The input impedance presented at this jack is 2MΩ. The maximum allowable signal level is +9.0 dBu. The MONO/L input routes to the Right input if no plug is inserted into R INPUT jack.

MONO/L INPUT

Instrument/Line level, 1/4” unbalanced input jack. Plug your instrument or output from another effects pedal into this jack. If you use just one input, we recommend using the MONO/L input. The input impedance presented at this jack is 2MΩ. The maximum allowable signal level is +9.0 dBu.

R OUTPUT

1/4” unbalanced output jack. The Right output signal is sent through this jack. In Bypass, the dry signal present at the Right input jack is output to the R OUTPUT jack. If a plug is not inserted into the Right input jack then the Left signal is output on the R OUTPUT jack in both effect and bypass modes. The source impedance of the R OUTPUT is 400Ω.

MONO/L OUTPUT

1/4” unbalanced output jack. The Left output signal is sent through this jack. In Bypass, the dry signal at the Left input jack outputs to the MONO/L Output jack. The source impedance of the MONO/L OUTPUT is approximately 400Ω.

BYPASS FOOTSWITCH & LED

Press the BYPASS footswitch to enable or disable the Big Muff effect. When the associated LED is lit, the Big Muff effect is enabled; when the LED is off, the unit is in buffered bypass mode.

PRESET FOOTSWITCH & LED

Press the PRESET footswitch to load or cycle through the 10 presets. When the associated LED is lit, the preset represented by the number on the display is loaded and enabled; when the LED is off, preset mode is off.
